Abstract:For an open quantum system we assume that we are able to set the system's environment temperature. We fix the time interval and let the system (further referred as the probing system) to evolve during this time in two different temperatures. We make a process tomography of the resulting dynamics (quantum channels ε1, ε2 related to the temperatures T1 and T2 respectively). We calculate then the values of α-fidelities for the pair of channels. We derive an inequality between the experimental data and the partiti… Show more
